MEDC PH1 Call Point | ATEX IECEx Explosion Proof & Hazardous Area Call Points
MEDC PH1 are ATEX call points with a double action pull handle has been designed for use in flammable atmospheres and harsh environmental conditions in ATEX & IECEx Zone 1 and Zone 2 hazardous area. The hazardous area call points, manufactured by MEDC, are manually operated fire alarms that are both simple to install and maintain in explosive atmospheres in onshore or offshore locations in accordance with the ATEX & IECEx certification and explosion protection levels.
The GRP enclosure of the hazardous area call point is suitable for use offshore or onshore where light weight combined with a high level of corrosion resistance is required.
The large “Lift” and “Pull” GRP handles can be operated effortlessly whilst wearing industrial gloves and require double action to raise the alarm, preventing accidental activation.

Hazardous Area Guide
♦ Definition : Potentially explosive atmospheres exist where there is a risk of explosion due to mixtures of gas/air, vapour/air, dust/air or other flammable combinations. Where electrical equipment has to be used in these areas, it must be so designed and constructed such that it does not create sources of ignition capable of igniting these mixtures.
♦ Area Classification : Process plants are divided into Zones (European and IEC method) or Divisions (North American method) according to the likelihood of a potentially explosive atmosphere being present. Note: North American legislation now allows Zones to be used to classify areas, where this practice is used it follows the IEC Zone method.
|European ATEX & IEC Classification||Definition of Zone or Division||North American Classification|
|Zone 0 (gases)||A hazardous area in which an explosive mixture is continuously present or present for long periods||Class I Division I (gases)|
|Zone 20 (dusts)||Class II Division 1 (dusts)|
|Zone 1 (gases)||A hazardous area in which an explosive mixture is likely to occur in normal operation||Class I Division 1 (gases)|
|Zone 21 (dusts)||Class II Division 1 (dusts)|
|Zone 2 (gases)||A hazardous area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short time||Class I Division 2 (gases)|
Class II Division 2 (dusts)
|Zone 22 (dusts)||Class III Division 1 (fibres)|
Class III Division 2 (fibres)

Eaton MEDC PH1 – Ordering Requirements
The following code is designed to help in selection of the correct MEDC hazardous area call point with ATEX approval and certification. Build up the part number of the call point by inserting the code for each component into the appropriate box.
MEDC have developed ATEX & IECEx call points designed for harsh and hazardous area conditions and where there is a risk of explosion due to the presence of flammable atmospheres both onshore and offshore – since 1975 MEDC have been designers and manufacturers of Explosion Proof alarm, signal, control and communications equipment.
Thorne & Derrick International, based in the UK, distribute the extensive range of Eaton MEDC ATEX Certified manual call points, visual, audible alarms, loudspeakers and telephones for hazardous area workplaces, including Zone 1 & Zone 2 explosive atmospheres.
